Did we ever establish if the count is of LC members (as in me, Red Dragon, Alexander) or of people from our past censuses? If it's ancestors, I think I may account for about 50 of them, as I got a (newly-discovered) second cousin once removed to join, and 'gave' her those to start her off.
I think the data comes from the Lost Cousins site, so that's all members of Lost Cousins and not just that subset which are members of this forum.
Good result getting your cousin to join, I have also made contact with a lost cousin from New Zealand, I've sent her a request (doesn't it take ages to select all the related family?) and she says she'll join at the weekend.
